We are in the process of implementing the JMS version and have made
significant changes to the Project Wonder. The biggest headache so far has
been wide variance in the abilities of the various JMS servers we have used
so far. We have tried openjms, Jrun, and Jboss.
OpenJms doesn't seem to work at all on RedHat 9 and higher. Seems to work OK
on Windows. The performance was shaky under load.
Jrun has a nice interface to create connection factories and topics. The
performance is pretty good. The documentation is next to useless, and there
is absolutely no ability to troubleshoot what is happening inside the JMS
server.
Jboss's JMS server provides better metrics than Jrun, however the JMX
console mbean interface is very generic and not intuitive. The only way to
figure out how to set it up is to buy the documentation. Haven't gauged how
good the performance is compared to Jrun.
We were able to get our CMS solution to use each of the JMS servers in an
acceptable manner, but not with significant changes to the Project Wonder
JMS implementation.
I think in general the JMS solution is a better alternative (especially in
the servlet deployment mode), but the quality and capabilities of the
various JMS servers are still lacking.
